Question

What are the coordinates of the vertices of the triangle under the translation (x, y) mc011-2.jpg (x + 1, y - 4)?

Answer 1

Original
(-1,1) (-4,1) (-4, 4) 

 translation (x, y) to (x + 1, y - 4)
(0,-3) (-3,-3) (-3, 0) 

answer
(0, -3), (-3, -3), (-3, 0)

Answer 2

it is c :

(0,-3), (-3,-3), (-3,0)

just take the X and Y of the coordinates of the original triangle and substitute it in the given equation (x + 1, y - 4)

try it out yourself it works :)
